(A) splitting apart continents - is a participle, therefore not correct for parallelism.
(B) the splitting apart of continents - noun because the article "the" changes the participle "splitting apart" into a noun, therefore it looks good
(C) split apart continents - verb, therefore no
(D) continents split apart - although this option starts with a noun, none of the other items on the list has a verb. therefore, "split" ruins the parallel structure.
(E) continents that were split apart- no where in the other items in the list has any relative pronouns

I would say B because we have a list of nouns, and some nouns have adjectives as well. Adjectives don't interfere with the nouns, so we have to look for an answer choice that would have either a noun or a noun with an adjective.

119) New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth’s magnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions.

(A) splitting apart continents
(B) the splitting apart of continents
(C) split apart continents
(D) continents split apart
(E) continents that were split apart

The imp thing in the question is check the construction : Cause -> Effect

New theories propose that catastrophic impacts of asteroids and comets may have caused
reversals in the Earth’s magnetic field,
the onset of ice ages,
splitting apart continents 80 million years ago,
and great volcanic eruptions.

Now these 4 should be parallel - the splitting apart of continents ( complex gerund mostly constructed by the +simple gerund+ of ..)

Sentence has “nouns” parallelism issue

(A) splitting apart continents (“splitting” acts as a participle, but require a noun – Eliminate it)
(B) the splitting apart of continents (“the splitting” is a gerund – Hold it)
(C) split apart continents (Not parallel – Eliminate it)
(D) continents split apart ( Not parallel – Eliminate it)
(E) continents that were split apart ( Not parallel – Eliminate it)

what's going on here? 2 elements in the list don't have "the", and 1 does? how come this is parallel? I think it should either be:

or
1) the reversals in the Earth’s magnetic field

Why "split" in B is not past participle and therefore parallel to "volcanic eruptions" ?

<splitting apart of continents> is a gerund phrase, not a participle.

How to differentiate between a gerund phrase and a participle phrase ...
Consider the following sentences.
Splitting apart continents, the force was responsible for the spread of super continents.
The underlined part is a present participle phrase which modifies "force"

The catastrophic impacts of asteroids and comets may have caused splitting apart of continents
The underlined part is a gerund phrase. It functions as a noun (object). It doesn't modify anything.
In option A, a participle phrase is used. So, it's not parallel to noun phrases or nouns.
In option B, the error is corrected by using the gerund phrase.

(A) splitting apart continents
(B) the splitting apart of continents
(C) split apart continents
(D) continents split apart
(E) continents that were split apart

They simply want to test if we understand a specific form of parallelism:

When you have >2 parallel entities, you have to have "and" before the LAST entity. Since "and" precedes "eruptions", we know that whatever we're supposed to put in needs to be parallel to the entities that come before. "Reversals in THE magnetic field... THE onset... [THE splitting apart]...AND great volcanic eruptions"

Only B works.

We want to parallel : the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions

Some parallel rules to remember here:
- Simple gerunds can NEVER be PARALLEL to complex gerunds
- ONLY complex gerunds CAN be PARALLEL to action nouns
- When an appropriate action noun exists, choose it over a complex gerund

Since the onset of ice ages is a complex gerund and that eruption is an action noun, we can only have an action noun (if it exists) or another complex gerund to complete the parallel

Answer A is a simple gerund and there is no appropriate action noun in the other answer choices. So look for a complex gerund-- answer B

of note: a complex Gerund Starts by (a, an, the) or adjective, followed by ing + “of” prepositional. ie : The accurate tracking of satellites (complex) vs the (simple version) Tacking Satellites accurately

Hello Members,
What is the concept here!
Do all the components here in the sentence needs to start with a noun? ...
or Having noun at the start of sentence good in parallelism?

Here you go: Check MGMAT SC chapter 10 or 11 if you have it

Concrete nouns vs action nouns vs complex and simple gerunds :

1/Concrete nouns: Refer to things, people, places dates… Ie: rock, continent, politician, holiday, week ...

2/Action nouns: Refers to action, they are formed from verbs Eruption, pollution, change, growth development etc

3/Simple Gerund: Include “ing”, presented as if the follow a verb
- ex: Tracking Satellites accurately is important
- Could be transformed into a working verb: I AM tracking satellites…

Complex Gerund: Starts by (a, an, the) or adjective, followed by ing + “of” prepositional
- ex: The accurate tracking of satellites is important…
- Of note: can also be under the form: the accurate satellites tracking – prefer the “of” version though

Parallel rules:

1.Concrete nouns are ONLY parallel to concrete nouns!
Wrong The bouquet was a giving of love
Correct The bouquet was a gift of love
- A giving is a complex gerund

2. Simple gerund are NEVER PARALLEL with complex gerunds
Wrong: I enjoyed drinking the water and the wine tasting
Correct I enjoyed drinking the water and tasting the wine
-drinking the water = simple gerund, the wine tasting = complex gerund

3. ONLY complex gerunds CAN PARALLEL with action nouns but when a proper action noun exists prefer it over a complex gerund
Wrong: The rebels demanded the withdrawal of the government forces from disputed regions, significant reductions in overall troop levels, raising the rebel flag on holidays, AND a general pardon
Correct: The rebels demanded the withdrawal of the government forces from disputed regions, significant reductions in overall troop levels, the raising of the rebel flag on holidays, AND a general pardon

Prefer an action noun over Gerund:
Wrong: The rebels demanded the withdrawal of the government forces from disputed regions AND releasing certain political prisoners (Simple Gerund used)
Wrong: The rebels demanded the withdrawal of the government forces from disputed regions AND THE releasing OF certain political prisoners (Complex Gerund used)
Correct: The rebels demanded the withdrawal of the government forces from disputed regions AND THE release OF certain political prisoners (action noun correctly used)
